Drug & Alcohol Rules + the Clearinghouse
This course covers the federal drug and alcohol program in 49 CFR 382 and Part 40: every required test type, the alcohol limits and timing rules, what counts as a refusal, and the return-to-duty road back. It also walks through the FMCSA Clearinghouse, including driver registration, full and limited queries, consent, and the CDL downgrade rule that took effect in 2024.
